fix(bin): remove cli from bin/docker-build

this commit removes mention of the cli from our `bin/docker-build`
script.

in #14360, we removed the cli
image from our published artifacts. moreover, invoking `bin/linkerd`
will call `bin/build-cli-bin`.

so, this commit removes both calls, to the now deleted
`bin/docker-build-cli-bin` script, as well as the `bin/build-cli-bin`
script. this lets the `bin/docker-build` script focus solely on docker
images.
